I’ve been chronically ill for 11 years now. I wasn’t really exercising basically at all for 8 of them then I started walking 3 years ago and jogging 1 year ago and cycling 6 months ago. My VO2 max was 52 at age 24. 40 when tested a year later after becoming sick. I had it retested a year ago and it was 36.5. But I ran a 5:59 mile a month ago so it is very likely higher now. But I haven’t been able to get it retested since it is expensive. But my general health has massively improved in the past 6 months. I cycle 10-20 miles a day every day. I had like diastolic heart dysfunction and tons of arrhythmia showing up years ago and had a heart monitor redone this year and the rhythm is back to what it looked like before I became ill. I’m still sick but just seems like I have more vitality anyway now despite that.
If you want to know your VO2 Max then you can do a Cooper Test for free at your local school running track. That won't be as precise as a metabolic lab test with a breathing mask but close enough.
Yeah I did that a few months ago and did 1.54 miles in 12 minutes. I think I could do more now. But that is so different from gas measured Vo2 max it makes me think it isn’t that accurate for my condition. Like perhaps my body is compensating
like I have permanent tendinopathy and muscles even still to this day lock up easily probably from mitochondrial dysfunction which would be explained by multiple lab findings I had like a really low lactate threshold compared to normal for my age
and I react to everything I eat with throat swelling eventually and constantly have to switch foods
nothing works long term I’ve tried everything I react to medications if taken long enough as well
